LiquidationExplanationStmt/ExplanationTxt0During 2025, the trustees of the Foundation voted to terminate and formally dissolve the Foundation. At that time, the Foundation began making liquidating distributions as part of the process to terminate as a private foundation. The Foundation completed liquidation of its remaining assets by paying out grants to various 501(c)(3) organizations described as public charities under Section 509(a)(1) along with final administrative and state filing fees. At the time of this filing, The Foundation has no remaining right, title, or interest in any assets and therefore does not owe any private foundation termination tax under Section 507(c) of the Internal Revenue Code. The $800 refund due to the Foundation from the IRS on this return will be split evenly between WriteBoston, 826 Boston, Inc and Grub Street Inc in 2026, once the refund is received. As this will be the final tax return filed by the Foundation, the $800 refund has been included in the total amounts paid to WriteBoston, 826 Boston and GrubStreet as is reported on this Form 990-PF, Part XIV.
